Online Keno Rules

Online Keno has the same rules as Keno that is played in Brick & Mortar casinos, so once you know the basics, you can play any kind of Keno you wish. You play with Keno cards or tickets, which are numbered from 1 to 80. You pre-select 20 numbers by clicking on the number with your mouse pointer. To deselect that number, you may opt to right click or, depending on the casino where you’re playing, there may be an option for you on the screen. You then determine how much money you would like to wager and how many games you would like to play. Then the draw commences.

The drawing takes place when 20 random numbers and selected by the computer. These numbers are highlighted on the Keno screen. The random number selection works just the same as with other casino games, in that a Random Number Generator computer software (RNG) is used to select the numbers. If your numbers match the numbers selected by the RNG, you win. The amount of your winnings depends on how many numbers are matched.
